Dynamics of the last glaciation in the southern part of the Kola region

During the last glaciation, the area of the modern White Sea was covered by the White Sea Ice Stream. In the southern part of the Kola region, this stream moved in an easterly and ortheasterly direction, and its northern periphery bordered on a low-active glacial lobe. During the maximum of the last glaciation and during the stages of its reduction, ice marginal formations of the Terskie Keivy were formed at this boundary. The Terskie Keivy contains both marginal push-moraine formations with glaciotectonic deformations and systems of marginal eskers. In the western part of the region, the position of the glacier margin is marked by a chain of glaciofluvial deltas. During the Younger Dryas cooling, several glacial lobes were active in the region, the marginal zone of which was mainly located in the periglacial-marine basin. The correlation of the ice marginal formations in the Kola region allows us to determine six main stages of glacier reduction in the Vepsa, Krestsy, Luga (Karelia), Neva (Syamozero) stages, as well as in the Salpausselkä Stage I and II.
